1,25 g of anhydrous iron(III) nitrate = 0,005 moles
How many MOLES of sodium nitrate are present in 2.85 grams of this compound ?
Hydrogen nitrate has a mass of 63.01 g/mol. In order to find the number of moles you divide the grams by the molar mass. 250/63.01 = 3.96 mol.
Ca(NO3)2 5.600 grams calcium nitrate ( 1mole Ca(NO3)2/164.1 grams)(2 moles NO3/1 mole Ca(NO3)2) = 6.825 X 10 -2 moles of nitrate ions -----------------------------------------------
there are two moles produced in potassium nitrate.
Calcium Nitrtae is Ca(NO3)2 and so there are two moles of nitrate per mole of calcium nitrate. Thus there are 2 x 2.50 = 5.0 moles of nitrate present.
How many MOLES of sodium nitrate are present in 2.85 grams of this compound ?
There are 0.13 moles in 20 grams of magnesium nitrate.
9 moles of Fe(No3)
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
15.451
23 grams iron ( 1mole Fe/55.85 grams) = 0.41 moles of iron
To calculate the number of moles from grams, you must divide by the substance's molar mass
how many moles are there in 56.0 grams of silver nitrate?
4.50 g(1/169.88) =.0265 mols
Hydrogen nitrate has a mass of 63.01 g/mol. In order to find the number of moles you divide the grams by the molar mass. 250/63.01 = 3.96 mol.
Ca(NO3)2 5.600 grams calcium nitrate ( 1mole Ca(NO3)2/164.1 grams)(2 moles NO3/1 mole Ca(NO3)2) = 6.825 X 10 -2 moles of nitrate ions -----------------------------------------------
388.grams Fe divided by mass of Fe 388.2g/55.85= 6.95moles of Fe
